Step-by-step explanation:
To find the number of ways that Paul can arrange his trophies, we can use the permutation formula.
The permutation formula is:
n = 9
k = 6
Now let's put them into the formula.
There are 60,480 different ways that Paul can arrange his trophies on the shelf.
Answer:
The equation that models the relationships between , the number of hours Mark reads, and ,
the number of pages of the book he reads is:
Step-by-step explanation:
Given:
Mark reads 42 pages every hour.
The number of hours is given by =
The number of pages is given by =
The equation can be modeled as:
where represents rate of change and
represents the y-intercept or the initial value.
Rate of change =
The initial value as Mark starts reading from 0.
So, the equation is:
Answer:
Primero, para un caso discreto, el índice de asimetría de Fisher se calcula como:
Donde:
xi son los i-esimos distintos valores de nuestro conjunto de datos.
M es la media
N es el numero de datos
ni es la frequencia absoluta de cada xi
Sx es la desviacion tipica
Podemos ver que en el caso discreto, escribimos el coeficiente con una sumatoria, lo cual realmente no podemos hacer para una variable continua.
Lo que si podemos hacer para una variable continua, es una integral, donde como esta vez tenemos una variable continua, podemos definir una función:
f(X) = frequencia absoluta para X.
Y escribir el coeficiente como:
Entonces si, es posible definir el índice.
